JIG FOR PREASSEMBLING SOIL PIPES Filed June 4 1951 ATTORNEY Patented June 29, 1954 UNITED STATES PATENT OFFICE JIG FOR PREASSEMBLING SOIL PIPES Howard J.`Fortner, Portland, Oreg.

. Application June 4, 1951, Serial No. 229,750

3 Claims.

This invention relates to jigs for preassembling soil pipes into relatively long sections.

The primary object of the invention is to provide a jig wherein lengths of soil pipe can-be aligned and leaded together at their joints previous to laying the same within the ground.

A further object of the invention is to provide means within the jig for assembling together soil pipe of various diameters so that their center lines will be alignment with one another.

These and other incidental objects will be apparent in the drawings, specification and claims.

Referring to the drawings:

Figure 1 is a plan view of my new and improved soil pipe jig showing how the soil pipe is maintained in alignment while the joints are being sealed.

Figure 2 is an end View of Figure l, taken on line 22.

Figure 3 is a fragmentary enlarged end sectional view, taken on line 3--3 of Figure 1.

Figure 4 is a fragmentary enlarged sectional view, taken on line 4-4 of Figure l, showing how the pipe is supported.

Figure 5 isa perspective detail of one of the clamping bolts for positioning and holding the movablel pipe supports.

Referring more specifically to the drawings:

The jig consists of a rectangular box-like body I, having sides 2 and ends 3 secured together by gusset plates 4. Intermediate pipe supports 5 are supported by rails 6 forming part of the side walls 2 of the jig. These pipe supports consists of movable cross members 5, having footings 1 located adjacent their lower sides or edges and these footings are adapted to slide and be supported on the rails 6.

Special clamping bolts 8, having feet 9 pass through these footings as best illustrated in Figures 3 and 4, coming down adjacent the edge of the rails 6 and having their feet 9 engaging the foot of the rails. These bolts have thumb nuts Il) for tightening them to the rails 6, positioning the supporting members 5 to any desired position along the rails E depending upon the length of pipe being secured together.

Located within the ends 3 and the pipe supporting members 5 are V-notches II, into which rest the soil pipes I2 which are being joined together by the usual process at their joints I3. In the event one of the soil pipes is of a smaller or different diameter, adapters I4 are employed, the adapters being secured to the ends 3 of the supporting members by the clamping bolts I5 working within slots I6 formed within the said ends and members 5, best illustrated in Figures 1 and 3. These adapters also have V-shaped notches II for receiving the soil pipes I2.

In the operation of my new and improved soil pipe jig, the supports 5 are positioned along the rails 6 so that the soil pipe can be supported thereby while the joints I3 of the pipes are being leaded together in the usual manner. The supports 5 and the ends 3 of the jig holding the pipe in alignment while this operation takes place.

Another function of my new and improved jig for soil pipes is to abut the enlarged female ends against the side of the supports 5 while making the connections between the fittings. This prevents the pipe from moving endwise while making the joint, as the operator has to tap the seal in place between the female part of the joint and the male by a hammer.

I do not wish to be limited as to the material that the jig is made from, but I have found that the same can be very well constructed of planking of approximately two inches in thickness,y although the jig could be made up from steel or other material.

I have also provided tool boxes I8 for holding the tools which are used to make and complete the leaded joints of the pipe. 'Ihe jig is preferably supported upon horses I9, bringing the same up to a height well adapted for the workmen to perform their work upon the pipes.

What I claim is:

1. A support for lining up pipe sections to be leaded, comprising a frame including parallel side bars and end bars, longitudinal runners secured'on the lower inner side of the longitudinal side bars, spaced-apart transverse bars between the longitudinal side bars, footings at the lower ends of the transverse bars slidably supported on the runners, the footings extending over and beyond the runners, adjusting screws mounted in the overhanging portion of footings, said screws extending downwardly and having their lower ends bent inwardly and clamped against the underside of the runners, whereby to adjust the transverse bars longitudinally on the runners, the upper edges of the transverse bars having aligned V-shape seats to receive sections of pipe, and an adaptor having a V-shaped seat smaller than the V-shape seat in the transverse bars and mounted for vertical adjustment on a transverse bar adjacent to and with its seat in line with a Vshape seat in the upper edge of the transverse bar.

2. A support for lining up pipe sections to be leaded, as defined in claim 1,. wherein the 3 adaptor is provided with screws passing through vertical slots formed in the transverse bar, and nuts on the screws to clamp the adaptor in adjusted position.

3. A support for lining up pipe sections to be leaded, comprising an open frame including parallel spaced-apart side bars, runners secured on the lower inner sides of said bars, spacedapart transverse bars between the side bars and supported on said runners, said transverse bars having aligned V-shaped seats in their upper edges, means for individually longitudinally adjustably positioning said spaced-apart transverse bars on said runners, and an adaptor adjustably positioned adjacent at least one of said V-shaped seats, said adaptor consisting of a block tted against the face of a transverse bar in line with a seat and having a V-shaped seat in its upper edge in registry with the seat in said transverse bar, the V-shaped seat in said adaptor being smaller than the V-shaped seat in the transverse bar.
